LIQUID-FUEL BURNER.

Application filed May 9,

This invention is directed to improvements in the construction, form and arrangement of the several parts of a liquid fuel burner of the gravity feed type, with the objects in view of providing a portable burner which will be very simple, safe and effective; which will produce a clean flame with a maximum heat for the fuel consumed; which can be readily installed; which will successfully burn the cheaper grades of liquid fuel, and

which will give a uniform heat.

A practical embodiment of the invention is represented in the accompanying drawings, in which Fig. 1 represents the burner in side elevation;

Figure 2 represents the burner in vertical central section:

The burner, generally speaking, comprises the liquid fuel containing hollow base member 1 and the cover member 2, both members being preferably of cast metal and having the following characteristics:

The hollow base member 1 is provided with inner and outer uprising annular flanges 3 and 4 forming between them an annular liquid fuel basin 5-. The outer annular flange is slightly higher than the inner annular flange. A depending annular flange 6 forms a continuation of the inner annular flange 3.

Liquid fuel may be fed by gravity from any suitable source of supply through the supply line 7 to the basin 5 in regulated quantities.

The cover member 2 is slightly greater in diameter than the basemember 1 and it is provided on its underside with a depending annular flange 8 having an upwardly and outwardly curved inner wall 9 and an upwardly and inwardly curved outer wall 10.

The cover member 2 is supported upon the base member 1' with the depending annular flange 8 located within the basin 5 with the.

bottom of the flange spaced from the bottom of the-basin, with the inner curved wall 9 spaced from the top of the inner uprising flange 3, and with the outer curved wall 10 of the flange spaced from the top of the outer uprising flange 4 of the base member.

In the present instance this spacing is accomplished by providing the cover member 2 with radially disposed lugs 11 which rest upon the outer flange 4 of the base member, saidilugs having vertical shoulders 12 ar- 1925. Serial No. 29,096.

ranged to prevent the lateral displacement of the cover member when in posit on on the base member. The lower line pipe 13 may be attached to the depending annular flange 6 of the hollow base member in any suitable manner.

In operation: The basin 5 in the base member is partly filled with liquid fuel and ignited. Air under low pressure is forced upwardly through the central bore 14 of the base member from any suitable source of supply, such as a blower, (not shown herein) which air is directed outwardly and downwardly between the uprising annular flange 3 of the base member and the inner wall 9 of the depending flange 8 of the cover member and thence upwardly and outwardly between the outer wall 10 of said depending flange and the outer uprising annular flange 4 of the base member. 1 I

It will be seen that the air is brought into intimate contact with the liquid fuel and ample oxygen is supplied thereto, to produce a practically perfect combustion of the fuel, thereby obtaining a most efficient heating effect therefrom.

What I claim is:

In a. liquid fuel burner, a hollow base mem ber provided with inner and outer upris ing annular flanges forming between them a liquid fuel basin, a liquid fuel supply therefor, and a cover member supportedby and spaced from the base member, said cover member being provided with a depending annular flange projecting into said basin below the tops of the inner and outer uprising annular flanges of the hollow base member, the inner and outer Walls of said depending annular flange being curved respectively, upwardly and inwardly and upwardly and outwardly to direct the air outwardly and downwardly between the inner uprising flange of the base member and the inner curved wall of the depending annular flange of. the curved member and thence upwardly and outwardly between the outer curved wall of said depending annular flange and the outer uprising flange of the base member In testimony, that I claim the foregoing as in invention, I have signed my name this 1st ay of May 1925. 1
